[PATCH v2 00/25] perf arm_spe: Extend operations

[Leo Yan]

This series enhances tooling to support new operations:

  - Support for MTE tag since Arm SPE v1.3;
  - Support for Advanced SIMD extension and SVE operations;
  - Support memcpy, memset and GCS operations;
  - Support extended operations for atomic, Acquire/Release and
    Exclusive instructions.
  - Enhance the data source for associated info, like floating-point,
    conditional, data processing, etc.

This series is divided into three parts:

  Patches 01 ~ 06: Support raw dump for new operations;
  Patches 07 ~ 17: Export the operation info into records, so that the
                   information can be later consumed by samples.
  Patches 18 ~ 25: Set the operation info into sample's data source and
                   SIMD flag, and updated the document.

This patch series is tested on FVP for native parsing and x86_64 for
cross parsing.

Changes in v2:
- Refined to use enums for 2nd operation types. (James)
- Avoided adjustment bit positions for operations. (James)
- Used enum for extended operation type in uapi header and defined
  individual bit field for operation details in uaip header. (James)
- Refined SIMD flag definitions. (James)
- Extracted a separate commit for updating tool's header. (James/Arnaldo)
- Minor improvement for printing memory events.
- Rebased on the latest perf-tools-next branch.
